2.1 问题
- 如图配置IP地址
- 启用 CHAP 认证,用户名/密码为:HuaWei/CCIE
- 确保R1和R2之间可以互通
2.2 方案
使用eNSP搭建实验环境,如图-2所示。

2.3 步骤
实现此案例需要按照如下步骤进行。
1)配置IP地址,确保设备互通
<Huawei>system-view
[Huawei]sysname R1
[R1]interface Serial 4/0/0
[R1-Serial4/0/0]ip add 192.168.12.1 24
[R1-Serial4/0/0]quit
<Huawei>system-view
[Huawei]sysname R2
[R2]interface Serial 4/0/0
[R2-Serial4/0/0]ip address 192.168.12.2 24
[R2-Serial4/0/0]quit
2)配置CHAP 认证
[R1]aaa
[R1-aaa]local-user HuaWei password cipher CCIE //创建用户名和密码
[R1-aaa]local-user HuaWei service-type ppp // 指定用户的服务类型为PPP
[R1-aaa]quit
[R1]interface Serial 4/0/0
[R1-Serial4/0/0]ppp authentication-mode chap //开启CHAP 认证
[R1-Serial4/0/0]ppp chap user HuaWei //指定用于CHAP认证的用户名
[R1-Serial4/0/0]quit
[R2]interface Serial 4/0/0
[R2-Serial4/0/0]ppp chap user HuaWei //被认证端使用的用户名
[R2-Serial4/0/0]ppp chap password cipher CCIE //被认证端使用的密码
[R2-Serial4/0/0]quit
[R2]interface Serial 4/0/0
[R2-Serial4/0/0]shutdown //关闭接口
[R2-Serial4/0/0]undo shutdown //打开接口
3)测试R1与R2之间的连通性
[R2]ping 192.168.12.1
